Where can I configure the network MTU (Maximum Transmission Unit) value? (Jumbo Frame)

For performance tuning, the MTU will set the default value to 9000 for optimum performance. However, some switches don’t support Jumbo Frame. If your switch does not support Jumbo Frame, please set the MTU value to 1500. The MTU value can be adjusted for all networking ports under the System\Network\Management Port and Data Port settings pages.
